When vertigo and hearing loss happen at the same time, it usually points to a problem in the inner ear, or less often in the nerve or brain. The inner ear handles both balance and hearing through closely connected systems, so when both symptoms appear together, particularly if one ear is affected more than the other, you’re looking at a much narrower range of possibilities than either symptom alone would suggest. This combination warrants prompt assessment, because some causes require urgent treatment to prevent permanent hearing loss, while others need investigation to rule out structural problems that won’t resolve on their own.
Why the Inner Ear Produces Both Symptoms
Your inner ear sits in the temporal bone of your skull and contains two distinct but neighbouring systems. The cochlea handles hearing, converting sound vibrations into electrical signals. The vestibular system, made up of three semicircular canals and two otolithic organs, handles balance and spatial orientation. They share the same blood supply through the labyrinthine artery, they’re bathed in the same fluids (endolymph and perilymph), and the eighth cranial nerve carries signals from both systems to your brain.
This proximity means that anything affecting the fluid balance, blood supply, nerve function, or structural integrity of the inner ear can affect both hearing and balance simultaneously. Clinically, when both systems are involved, you’re usually dealing with either a fluid problem, a vascular event, inflammation, or a growth. Each has different implications and timelines for treatment.
Conditions That Cause Both Vertigo and Hearing Loss
Meniere’s disease is the classic example and probably accounts for a significant portion of patients presenting with episodic vertigo and fluctuating hearing loss. You get attacks of severe rotational vertigo lasting 20 minutes to several hours, fluctuating low-frequency hearing loss (particularly noticeable as a fullness or pressure in one ear), tinnitus, and aural fullness. Between attacks, you might feel completely normal initially, but the hearing loss tends to become permanent and affect more frequencies as the disease progresses.
Diagnosis follows criteria published by the Bárány Society: two or more spontaneous episodes of vertigo lasting 20 minutes to 12 hours, audiometrically documented low- to medium-frequency sensorineural hearing loss in one ear on at least one occasion before, during, or after an episode of vertigo, fluctuating aural symptoms (hearing, tinnitus or fullness) in the affected ear, and no better explanation for the symptoms. We see this most commonly in people aged 40 to 60, though it can start earlier. The hearing loss is what differentiates Meniere’s from other causes of episodic vertigo, and it’s why you need a proper audiometric assessment, not just a subjective sense that your hearing might be down.
Vestibular schwannoma (often still called acoustic neuroma) is a benign tumour growing on the vestibular portion of the eighth cranial nerve. The presentation is typically gradual: unilateral hearing loss that progresses over months to years, continuous tinnitus in one ear, and unsteadiness rather than acute spinning vertigo. Some patients do experience vertigo, but it’s less dramatic than Meniere’s because the tumour usually grows slowly enough that your brain compensates. What brings people in is often the hearing loss or tinnitus, and it’s the pattern on audiometry, particularly poor word recognition scores out of proportion to the pure tone loss, that raises suspicion. This is one reason why one-sided or asymmetric hearing loss always needs investigation. MRI with contrast is the gold standard for diagnosis.
Sudden sensorineural hearing loss with vertigo is an ENT emergency. If you wake up with sudden hearing loss (usually defined as 30 dB or greater loss across three contiguous frequencies occurring within 72 hours) and significant vertigo, you need medical assessment the same day or the next day. The vertigo suggests the problem involves more than just the cochlea: possible causes include labyrinthitis or a disruption to the blood supply of the inner ear. Treatment with corticosteroids is time-sensitive and works best when started early, ideally within the first few days. People who wait for it to resolve on its own can miss the period when treatment is most likely to help.
Labyrinthitis and vestibular neuritis often get confused, but the difference matters. Vestibular neuritis affects only the balance portion: severe vertigo without hearing loss. Labyrinthitis involves both the vestibular system and the cochlea, so you get vertigo plus hearing loss. Both are thought to be viral in many cases. The vertigo is severe and constant for the first few days, then gradually improves, but hearing loss from labyrinthitis may or may not recover fully.
When Vertigo and Hearing Loss Aren’t Directly Connected
This is equally important to understand. BPPV (benign paroxysmal positional vertigo) is the most common inner ear cause of vertigo, but it doesn’t cause hearing loss. If you have BPPV and hearing loss, they’re separate problems that happen to coexist, usually because both become more common with age. BPPV is purely mechanical: calcium crystals dislodge from the utricle and migrate into the semicircular canals. Treatment is the Epley manoeuvre or similar repositioning techniques. If someone tells you their BPPV is causing hearing loss, they’ve either been misdiagnosed or they have two separate conditions.
Vestibular migraine is increasingly recognised and probably underdiagnosed. Patients get episodic vertigo or dizziness related to migraine, but hearing loss is uncommon and, when it occurs, is usually mild and temporary. You might experience aural fullness or sensitivity to sound during an attack, but audiometry between attacks is usually normal. If it’s not, you’re looking at something else in addition to the migraine.
What Actually Happens in Assessment
If you present with both vertigo and hearing loss, you should expect to see both an audiologist and an ENT specialist, often in quick succession depending on severity. The audiologist’s role is to document and characterise the hearing loss through comprehensive audiometry: pure tone thresholds across frequencies, speech discrimination testing, tympanometry to rule out middle ear involvement, and often acoustic reflex testing. For vestibular schwannoma screening, auditory brainstem response (ABR) testing used to be standard, but MRI has largely superseded it for definitive diagnosis.
The pattern of hearing loss tells us a lot. Low-frequency sensorineural loss that fluctuates points toward Meniere’s. Unilateral high-frequency loss with disproportionately poor word recognition raises suspicion for retrocochlear pathology like vestibular schwannoma. Sudden profound loss with vertigo suggests labyrinthitis or vascular event.
Balance testing, arranged through your ENT or a specialised vestibular clinic, may include videonystagmography (VNG) or electronystagmography (ENG) to objectively measure eye movements during various positional tests, caloric testing to assess how each vestibular system responds to temperature changes, and video head impulse testing (vHIT) to evaluate the function of each semicircular canal. The ENT will also examine the ear to rule out middle ear pathology and may order imaging: CT for bone detail, MRI for soft tissue and neural structures.
When to Seek Urgent Care
You need same-day or next-day assessment if you have sudden hearing loss with or without vertigo, particularly if it’s unilateral. This is not a “wait and see” situation. The sooner treatment begins, the better the chance of recovery.
Call 000 or go straight to an emergency department if vertigo comes on suddenly together with any of these: slurred speech, weakness or numbness in the face, arm or leg, double vision, difficulty walking, or a sudden severe headache. Rarely, a stroke can cause sudden vertigo and hearing loss, and it needs emergency treatment.
Seek prompt (within days) assessment if you have new-onset vertigo with hearing loss, unilateral hearing loss that’s gradually worsening, or episodic vertigo with fluctuating hearing or tinnitus in one ear. These aren’t necessarily emergencies, but they need proper investigation, and delays can mean missed treatment windows or progression that could have been monitored.
Standard appointment timelines are appropriate for chronic unsteadiness with longstanding stable hearing loss, or vertigo without any hearing symptoms.
The Practical Path Forward
If you’re experiencing both symptoms, book a comprehensive hearing assessment while arranging an ENT consultation (usually through your GP). The audiometry results will be needed for the ENT assessment anyway, and having that objective documentation from the outset prevents delays. At The Audiology Place, a full diagnostic assessment takes 90 minutes and provides the baseline data that every subsequent specialist will want to see.
Be prepared to describe your symptoms precisely: Is the vertigo constant or episodic? If episodic, how long do attacks last: seconds, minutes, or hours? Is the hearing loss constant, fluctuating, or progressive? One ear or both? These details matter enormously for differential diagnosis.
Understanding that vertigo and hearing loss occurring together point to inner ear involvement gives you a framework for seeking appropriate care and asking the right questions. The inner ear is small, intricate, and unforgiving of delayed treatment in some conditions, but with proper assessment and management, most causes can be either treated or effectively managed. The key is recognising that this combination of symptoms deserves investigation, not reassurance that it will pass on its own.
